Myositis ossificans traumatica (MOT) of the elbow is a rare entity in children. It is a self-localized tumor-like lesion of the elbow causing ankylosis due to humeroulnar bridging. It is a complication arising due to a muscle contusion injury.
We report a case of an 8-year-old female who presented with a 2-year history of a fixed elbow and a palpable bony mass. The examination confirmed a confined bony mass on the anterior aspect and ankylosis of her left elbow. On confirmation of the diagnosis, an en bloc excision was performed. Follow-up every 2 weeks for the first 3 months, then once a month for the next 6 months, and finally once every 6 months for the next 4 years. The affected limb functioned well, with no sign of recurrence.
MOTs of the elbow in children are a rarity, and excision of the lesion without delay is an effective management strategy for a satisfactory outcome.
儿童肘部创伤性骨化性肌炎（MOT）较为罕见。它是肘部一种自限性肿瘤样病变，因肱尺关节桥接导致关节强直。它是肌肉挫伤损伤引起的一种并发症。
我们报告一例8岁女性，有2年肘部固定及可触及骨性肿块的病史。检查证实左肘前方有局限性骨性肿块及关节强直。确诊后，进行了整块切除。最初3个月每2周随访一次，接下来6个月每月随访一次，最后4年每6个月随访一次。患侧肢体功能良好，无复发迹象。
儿童肘部MOT罕见，及时切除病变是获得满意结果的有效治疗策略。
